space after and the second's space before, as Word does by default. Word adds them instead when the document's compatibility options include w:doNotUseHTMLParagraphAutoSpacing. Measured in Word with five paragraphs of 12 pt before and after: 24 pt between them with the option, 12 pt without, the same in compatibility modes 14 and 15. A 60-page report with the option lost 6 pt per paragraph, about 60 pt on its cover. The option is read, laid out in the body and in boxes, and saved back.
